Module 6: Choropleth Maps
During week 6, students explored choropleth mapping. This is the most
widely used type of thematic map for quantitative data. Choropleth maps are
used for normalized data - in contrast to proportional symbol maps which are used
for total counts. Choropleth maps are also one of the most complex type of maps
to design. You have to make decisions on normalization, classification and
color ramps, among other things. Different design decisions can result in a
very different map for the same data, so more than ever it is important to be
aware of your design process.
We would like to specifically
recognize Jeremy Mullins for his excellent cartographic work in this module and
the class so far. In addition to his lab deliverables being
professional and well organized, he has shown an eye for creativity and
critical thinking. This makes Jeremy’s work stand out because good cartography
is both an art and a science. For example, in the choropleth lab title choice for
a population change map of Georgia draws the map readers in by providing a
slightly-tongue-in-cheek, but geographically accurate, description of the maps’
purposes.
Jeremy’s blog post is also well written and shows the corresponding maps he has
produced for each lab.
Jeremy is a Graduate Teaching Assistant for the GIS Certificate Program and we are so happy that he chose UWF! Keep up the great work Jeremy!
